IMSAI Restoration Suggestions?

I'm hoping someone on the list can help. I rescued an IMSAI 8080, as well as a large (and heavy) dual 8" drive chasis (fully enclosed). The IMSAI is stocked full of cards which I haven't figured out what they are yet as they're in pretty tight and I'm afraid of breaking something yanking them out. I'm assuming at least one of them is a terminal interface card and another an interface for the drives. Here's the two problems with the unit though: 1) It appears to be missing the main processor card. Everything else looks mint, including the control panel and the ribbon from the pannel to the control/processor card is intact as well. 2) The people (the university janitorial staff) that were throwing it out, cut off the power cord. Hence there is a stub of a cord connected to the power supply now running out the back. I'm basicly looking for any help/suggestions in how to indentify the cards and what I can do to fix the other two problems. Thanks! Marty
